Operating and Support (Cost)

A Life Cycle Cost (LCC) cost category that includes all personnel, equipment, supplies, software, and services, including contract support, associated with operating, modifying, maintaining, supplying, training, and supporting a defense acquisition program in the DoD inventory. This includes costs directly and indirectly attributable to the specific defense program; i.e., costs that would not occur if the program did not exist, such as mission personnel, unit level consumption, fuel and energy resources, intermediate level maintenance, depot maintenance, contractor support, sustaining support, and indirect support. These activities are not bound to a life cycle phase or appropriation category.
